春大豆春播和秋播性状间的相关性

以３５个春大豆品种（系）为材料，研究了各主要农艺性状春播和秋播间的相关关系．结果表明，春大豆主要农艺性状如株高、单株粒数、主茎节数、每荚粒数、有效分枝、总荚数、有效荚数、营养生长期和全生育期等性状在春播和秋播间存在着显著或极显著的相关．表明秋播条件下对这些主要农艺性状的选择效果较好，而对单株产量、百粒重等性状的选择效果不佳．

Studies on correlation between spring sowing and autumn sowing characters of spring soybeans. Journal of Zhejiang Agricultural University

Studies on correlation between spring sowing and autumn sowing characters using 35 spring soybean varieties were conducted. The results showed that correlation coefficients ( r ) were significant or extremely significant between spring and autumn sowing for main agronomy characters such as plant height, seeds per plant, nodes per plant, seeds per pod, effective branches, total pods, effective pods, vegetative growth period and total growth period. It was suggested that relatively better results would be obtained using these parameters but not for characters such as yield per plant and 100 seed weight under autumn sowing condition.
